I am trying to set up subscriptions in a premium capacity or paginated reports with paramters, but every time I try to save the subscription, all the parameters that are configured (most are default) disappear from the subscription. I don't even have a section to update the parameters at all. I've attached a screenshot of an interesting error that pops up after attempting to save the subscription with the parameters:
To reproduce this, steps are pretty simple:
Have a paginated report with parameters that can be null
Execute the paginated report in the service
Create a subscription for that report with the parameters set to the default value (some are null and some are not)
Check the subscription and you will see that no parameters are present in the subscription
One thing that makes me suspect this is a bug is that there are older subscriptions that have the same exact steps taken above from 1 month ago that are working as expected. We also created another subscription for a different report that does not take a null parameter and that report subscription worked as expected.
I also do the testing and the process as the following shows:
You can see when I set parameter as current value and not choose"default", it can be applied successfully.
At the same time, I found that your error message say" you need to return to report to set all requiered parameter values", so I think there are some parameter values that must be assigned in order to be successfully applied to the subscription.
